A 49.0-kg body is moving in the direction of the positive x axis with a speed of 268 m/s when, owing to an internal explosion, i

t breaks into three pieces. One part, whose mass is 9.5 kg, moves away from the point of explosion with a speed of 466 m/s along the positive y axis. A second fragment, whose mass is 5.0 kg, moves away from the point of explosion with a speed of 440 m/s along the negative x axis. What is the speed of the third fragment? Ignore effects due to gravity.

On a certain map, every 3 cm represents 6 km on earth surface. Which ratio represents the scale of the map, which shows how the
damaskus [11]

Answer:

1 : 2 cm/km  or \frac{1}{2} \, \frac{cm}{km}

One cm represents 2 km.

Explanation:

If 3 cm represents 6 km on the earth, the ratio to consider is: 3 : 6  cm/km which is the same as:  

1 : 2 cm/km  or \frac{1}{2} \, \frac{cm}{km}

One cm represents 2 km.

An astronaut on a strange planet finds that she can jump a maximum horizontal distance of 14.0 m if her initial speed is 2.20 m/
pochemuha

We have the equation of motion

                          v^2 = u^2+2as , where v is the final velocity, u is the initial velocity, a is the acceleration and s is the displacement.

In this case initial velocity = 2.20 m/s, final velocity = 0 m/s, displacement = 14 m

On substitution we will get 0 = 2.20^2+2*a*14

On solving we can find the acceleration value as -0.173m/s^2

So free fall acceleration = 0.173m/s^2

A car can accelerate from rest to 28 m/s and travels 280meters. How long does this acceleration take?
Reika [66]

Answer:

a=1.4m/s^2

Explanation:

From the question we are told that

Velocity v=28m/s

Distance d=280

Generally the Newtons equation for motion is mathematically given as

Acceleration

v^2=2as

a=\frac{V^2}{2s}

a=\frac{28^2}{2*280}

a=1.4m/s^2
